The game itself is running fine, however there's a fairly serious problem I have with my dual monitor setup. Put simply, in another game (dota 2 for example), when I enable the fullscreen (not windowed fullscreen) option, the mouse cursor properly sticks inside the window on just my main monitor where the game is being played.

However in GC3 I am able to move my mouse cursor outside of the game and onto my second desktop/monitor freely - the becomes a very annoying problem when I am trying to lazily scroll to the right of the map by just moving the mouse to the right, it moves onto my second desktop. It is as if the game is running in "fullscreen windowed" mode and not true fullscreen.

I have also had this happen in SoSE, another stardock game... but it doesn't happen in any other game I play unless I have fullscreen windowed mode specifically enabled. Can you guys check and make sure that fullscreen mode is running properly? Or possibly add both a fullscreen and fullscreen-windowed mode option?
